WATER-HEATING ATTACHMENT. I

Specification of Letters Patent.

Application filed July 3, 1917. Serial No. 178,476.

To all'whom t may concern.'

Be itknow'n that I, WESLEY M. HAMIL- TON, a citizen of the United States, residing at Tampa., inthe county of Hillsborough and State of Florida, have invented certain new and useful Improvements in Water- I-Ieating Attachments, of which the followinis a specification.

his invention relates to water heating devices, particularly to water heaters associated with cook stoves, andhas for its object the provision of a water heating attachment for gas ranges of the type having,

a plurality of horizontally disposed burners at they top.

An important object is the provision of a water heating attachment comprising a plurality of coils so supported and positioned as not to interfere to the vslightest degree with cooking.

Another object is the provision of a water heater and storage tank associated therewith so arranged that a` positive circulation of water will be maintained at all times, the

Water inlet and outlet tubes being so posi-1 tioned yin different planes that there can be no backing up o f heated water into the feed plpe.

Other objects and advantages such as simplicity and cheapness in the mounting of the coils, efficiency in operation, and the general improvement of- `the art, will be carefully brought out in the following description and illustrated in the accompanying drawings, in which;

Figure 1 is a vertical longitudinal sectional view through a gas stove equipped with my device,

Fig. 2 is a front view thereof, parts being broken away and in section,

Fig. 3 is atop plan view, and Fig. 4 is a detail vview illustrating the mounting of the coils.

Referring more particularly to the drawl ings, the numeral 1 designates a gas range having the usual oven 2 provided with burners 3 and 4, and the top plate 5 provided with the usual holes 6y below which are disposed the ordinary burners y7, the' holes being closable by the usual grids 8.

.This structure is old and forms no part of the present invention.

Mounted on a. suitable bracket 9 atthe rear of the stove is a water tank 10 of convenient size and shape and provided with draw oil" cocks 11 anda suitable filling openving. From the lower portion of the tank a pipe 12 extends down below the stove and then upwardly into the oven burner compartment where itis coiled about the burner 3 and then y.across and about the burner 4, after which the pipe extends upwardly through the top plate 5 and up to the top portion of the tank into which it empties.

Extending horizontally from the bottom of the tank 10 is a pipe 13 which has its outer end 14 bent down nd disposed within a feed opening in the lop of a four way connection 15 which is disposed at the center of the top portion of the stove at the maximum distance below the burners 7. From this connection extend four pipes 16, each of which is inclined. upwardly to a point above the outer edge of a burner 7 and immediately below the grid 8, at which position it is coiled twice upon itself to form a heating coil 17 having its convolutions in Patented Nov. 6, 1917.,-

horizontal alinement. Each-pipe 16 then eX- tends horizontally below the top plate -to a point adjacent the rear edge thereof at which position each pipe leads upwardly along as at 18 and empties into the tank 10 at the upper end. In order that the assembled upper portions of these pipes may be hidden from view and also protected from injury I provide a hood or shield 19 disposed upon thetop plate, surrounding the upper portions 18 of the pipes and extending adjacent the tank l0.`

In order that the coils-17 may be properly supported-in position, I provide a pluralityl of clips v20 at convenient intervals. Each of these clips comprises a short strip of metal disposed below one side of a coil and havingits ends curved upward as at 21 to prevent shifting, and held in place by a Iscrew 22 extending downwardly from a downwardly foran appreciable distance as shown.

In the operation of the device it will be v seen that as the tank and pipes are primarily.

full of water, lighting any of the burners will cause the coil thereabove to become heated, consequently heating the water therein. As the water is heated it will pass upwardly through the pipes into the tank in laccordance with the well-known principles of physics. 0f course, the more burners used, the quicker the Water will be heated. It will be noted that the fourway connection supplying water to the coils is considerably below the coils, therefore insuring the prevention of backingup of the heated water into the feed pipe, and thereby providing proper circulation. Furthermore, it will be observed that the initial convolution of each coil is nearest the burner, thereby causing'the coolest water to receive the most intense heat.

From the foregoing description and a 'study of the drawings 'it will be appa-rent that I have thus provided a simple attaching ment for gas ranges whereby water may be rapidly heated without in any way interferminimum expenditure of fuel.

I-Iaving thus described my invention, I claim 1. In combination with a. gas stove having a top plate and a plurality of burners disvposed therebelow; a tank, a feed pipe communicating with the bottom of said tank and disposed below said burners, a heating coil disposed above each burner and connected with culinary operations and with the with said feed pipe, an outlet pipe connected with each coil and extending along the bottom of said top plate and upwardly through an opening therein and discharging into the upper portion of said tank, all of said outlet pipes being substantially parallel above said top plate, and a sleeve disposed upon said top plate, surrounding said outlet pipes and .extending vertically to a point adjacent the entry of said outlet pipes into said tank.

2. In combination with a gas stove provided with a top plate and a plurality of burners spaced below said plate; a reservoir tank, a feed pipe communicating with the ing in an 'outlet pipe extending along said top plate and upwardly therethrough and along said tank and communicating with the top portion of said tank.

In testimony whereof I hereto aflix my signature.

WESLEY MACK HAMILTON.
